Abstract

Pour permettre le transfert d'assemblages de combustible nucléaire irradiés au-dessus d'un liquide de refroidissement dans lequel baignent normalement ces assemblages, tout en assurant leur refroidissement, il est proposé un ringard 10 comportant un tube guide 12 formé de deux parois coaxiales 12a, 12b entre lesquelles circule de bas en haut le liquide prélevé à la partie inférieure du tube guide par une pompe 38 ou un système équivalent. Le liquide de refroidissement s'écoule ensuite par gravité dans l'assemblage 16 suspendu en grappin 14 logé dans le tube guide. Un tel ringard, utilisé dans un réacteur nucléaire à neutrons rapides, réduit de façon sensible la hauteur de la cuve du réacteur et, par conséquent, le coût de ce dernier.To allow the transfer of irradiated nuclear fuel assemblies above a cooling liquid in which these assemblies normally bathe, while ensuring their cooling, a corny 10 is proposed comprising a guide tube 12 formed of two coaxial walls 12a. , 12b between which circulates from bottom to top the liquid withdrawn from the lower part of the guide tube by a pump 38 or an equivalent system. The coolant then flows by gravity into the suspended grapple assembly 16 14 housed in the guide tube. Such old-fashioned use in a fast neutron nuclear reactor significantly reduces the height of the reactor vessel and, consequently, the cost of the latter.
